A kitchen hood has a first housing and a second housing that slides into and out of the first housing to adjust a length of the kitchen hood. The first housing has a fan to suction air, an outlet, and an air quality sensor assembly to continuously detect air quality in a kitchen. The second housing has an inlet and suction grill through which air is suctioned, a steam cleaning assembly to automatically steam clean an interior of the kitchen hood, and a height sensing assembly to sense a height of cookware seated on a cooktop surface below the second housing. The kitchen hood may be lengthened or shortened based on the sensed height of the cookware, and a speed of the fan and the height of the kitchen hood may be automatically adjusted based on detections by the air quality sensor assembly.

According to an aspect of the present disclosure, a ventilation system includes at least one user directed component and a plurality of sensors configured to detect a plurality of control gestures within a gesture field designated for presentation of control gestures by a user. The ventilation system may further be configured such that a control gesture of the plurality of control gestures is presented within the gesture field for detection of said control gesture by the plurality of sensors, and the plurality of sensors recognizes the control gesture as corresponding to an operation of the at least one user directed component. The ventilation system may still further include a controller for polling the plurality of sensors and converting a recognized control gesture to a command signal for operating the at least one user directed component.

An appliance or light assembly may include a bulb bracket within which a light bulb is receivable and a wall panel. The bulb bracket may include a cylindrical base defining a base radius and a plurality of resilient tabs. The plurality of resilient tabs may be selectively deflectable inward. The wall panel may define an assembly aperture. The assembly aperture may include a plurality of arc segments and a plurality of expanded notches. The plurality of arc segments may be spaced apart from an aperture axis. The plurality of expanded notches may be circumferentially spaced apart by the plurality of arc segments. The plurality of expanded notches may extend outward from the plurality of arc segments. Each expanded notch may define an angular distance. Each expanded notch may include a curved segment and a blunt segment.

A ventilation hood includes a main frame which faces an appliance accessible from a front of the appliance, the main frame defining a through-hole passing through the main frame, a motor module on the main frame and configured to suck in air through the through-hole, the motor module including a duct, a motor having an axis, and an exhaust fan driven by the motor and defining a blowing direction perpendicular to the axis of the motor, and a controller configured to control operation of the ventilation hood and a rotation velocity of the exhaust fan. The axis of the motor is in a direction from the front of the appliance to a rear of the appliance which is opposite to the front. The controller is on the main frame and at a front of the duct which corresponds to the front of the appliance.

An over-the-range appliance mountable over a cooktop appliance is provided. The over-the-range appliance includes a cabinet comprising a bottom panel defining a central aperture, a lighting box mounted within the central aperture. The lighting box defines a lighting recess and one or more light sources are mounted to the lighting box and are positioned within the lighting recess. A diffuser plate is positioned over the one or more light sources and encloses the lighting recess.

Disclosed is an induction ventilation system for air supply and exhaust, including: an upper plate that has an induction heating portion thereon and a lift hole in a rear portion thereof; a vertically movable unit that moves up and down through the lift hole and is equipped with a filter; an air suction and discharge unit including a chamber with an oil drain hole, a flexible duct connected between the vertically movable unit and the chamber, an air suction fan, and a discharge pipe through which indoor air drawn by the air suction fan is discharged outside; a grease tray installed under the chamber to collect grease that is condensed on the surface of an air suction passage; and an air supply hood that guides the indoor air to the air suction passage by supplying air to the upper plate using an air supply fan.

A kitchen vent hood includes a body defining an inclined front face having a vent inlet thereon. A front panel assembly is hingedly coupled with the body and extends along the inclined front face of the body. The front panel assembly includes a vent grate extending across a width of the vent hood body and at least partially covering the vent inlet. A panel bracket extends forward from the vent hood body at a position adjacent to and above the vent grate. An upper panel is coupled with the panel bracket and extends oppositely from the vent grate to define an open space adjacent the front face of the body. A light source is mounted within the panel bracket and is positioned to direct light outwardly therefrom and over the vent grate.
